A single technique to measure formation pressures at lost circulation zones while drilling has been enveloped and tested. To minimise loss of rig time and maintain well condition, a method has been developed where measurements are made inside the drill pipe using normal mechanical downhole pressure gauges . Tests have shown that the technique can measure formation pressure within the normal gauge accuracy.
